Owain has a habit of speaking in an overly theatrical fashion that some people find tiresome to deal with. He is somewhat preoccupied with the idea of being a hero and seeks the fabled sword the Missiletainn in his quest. Owain's supports reveal that he is a bit of a writer, and always tries to write other characters into his stories the way he sees fit to do it. He also has the habit of giving odd names to weapons and moves, the names of which are all references to past Fire Emblem games. He is quite proud of his heroic lineage. He is the most hot-blooded member of the army.

In an alternate future, where he doesn't go back in time, he is killed in battle sacrificing himself so that Brady and Yarne can escape with two of the stones for the Fire Emblem. Spoiler - Click to see/hide
